C.F. Franco Ethiopien 0-6-0 Locomotives in Ethiopia
Class Details by Steve Llanso of Sweat House Media
Class 51 (Locobase 9976)
Data from JP Crozet's Franco-Ethiopian Railway site, [
], last accessed 28 November 2011.
The first four of these little tanks (works numbers 40-43) were named Djbouti, Harrar, El Bah, & Seine (the last might reflect nostalgia on the part of the French owners of this railway). These arrived in 1899. Eleven years later, 4 more made the journey, but these apparently were not named.
The heating surface given in the diagram allows no surface area for the firebox if the outer dimension of the fire tubes is used to calculate tube heating surface. If the inner diameter of 35 mm was used in the calculation, which may have been so, then the firebox heating surface came to 5.1-5.35 sq m (55-58 sq ft ).
